I never planned for my sister to shove a vibrator between my legs that night, but once it started there was no stopping it. We were both adults, both home from college for the weekend, both a little drunk on cheap wine and the fact that our parents were out of town. The house felt too quiet, too big, so we ended up in my old bedroom with the door locked, laughing about stupid shit until the laughter turned into something heavier.
She had always been the bolder one. “You still got that little bullet I gave you last year?” she asked, leaning against the dresser with her shirt half unbuttoned. I nodded. She grinned, walked over, and pulled it out of my nightstand like she owned the place. “Show me how you use it.”
I should have told her to fuck off. Instead I stripped down to my panties right there on the bed, heart hammering. She watched without blinking. When I clicked the toy on, the low buzz filled the room. I pressed it over the thin cotton and felt my clit jump. She didn’t look away.
“Take the panties off,” she said, voice low and dirty. “I want to see.”
I hooked my thumbs in the waistband and slid them down. My pussy was already wet, lips parted. She grabbed the vibrator from my hand and climbed onto the bed between my knees. “Spread wider.” I did. She ran the buzzing tip straight up my slit, slow and deliberate, coating it in my slick. Then she pressed it hard against my clit and held it there.
“Fuck—Lila,” I gasped. The sensation was immediate and brutal. My hips jerked. She didn’t ease up. She just circled the toy, grinding it in tight little motions that made my thighs shake. “You like that, don’t you? Your own sister making you drip.”
I moaned instead of answering. She knew the answer anyway. She pushed two fingers inside me without warning, curling them while the vibrator stayed glued to my clit. The double pressure made my back arch off the mattress. I could hear how wet I was, the filthy sound of her fingers pumping in and out while the toy buzzed relentlessly.
“Tell me you want it harder,” she demanded.
“Harder,” I choked out.

“Make me come, please.”
She laughed, low and mean, and turned the toy up another notch. The vibration went from steady to punishing. My clit throbbed under it, swollen and oversensitive, but she wouldn’t let me pull away. She pinned my hip with her free hand and kept working both the toy and her fingers until I was panting and swearing.
When I came the first time it hit like a punch. My cunt clamped around her fingers, juices running down her wrist. She didn’t stop. She kept the vibrator pressed tight, dragging the orgasm out until I was shaking and trying to close my legs. “Too much,” I whimpered.
“Shut up,” she said, voice rough. “You’re not done.”
She flipped me onto my stomach, pulled my hips up, and shoved the vibrator back against my clit from behind while she fingered me deeper. The new angle made everything feel thicker, dirtier. I buried my face in the pillow and moaned like a slut while my sister used the toy on me like she was trying to break me. Every time I thought I couldn’t take more, she turned the speed up or twisted her fingers just right.
By the third orgasm I was sobbing into the sheets, legs trembling, pussy swollen and dripping. She finally eased the toy off but kept her fingers moving slow and deep, letting me come down. When she pulled them out she licked them clean, eyes locked on mine.
“Next time,” she said, “I’m using the bigger one on you. And you’re going to beg for it.”
I lay there wrecked, cunt still pulsing, knowing she meant every word. And I already couldn’t wait.
